Len confirmed before the last series that the 2016 show would be his last on British TV.

He said: "This adventure began when I was 60 and now that I’ve reached my 70s, I’ve decided after this year it’s time to hand the role of Head Judge to someone else."

No replacement has been confirmed yet but current Strictly pro Anton Du Beke has reportedly been offered a screen test while Strictly chief choreographer Jason Gilkison has also been tipped as a potential replacement.

In fact, Jason is now one of the more likely candidates according to the bookies after some big bets.

“This gamble has taken us by surprise and if it continued Jason could leapfrog Anton Du Beke, who’s dream of becoming a Judge could be in tatters,” said William Hill spokesman Rupert Adams.

Alongside Anton and Jason, others tipped for the role include ballroom expert Gary Edwards, current and former pro dancers Brendan Cole and Karen Hardy, as well as ex judge Arlene Phillips.

Strictly host Tess Daly previously said the wait until a name is confirmed won't be long now.

Speaking at the National Television Awards, Tess said: "We don't know [who it is] - it's still under discussion."
